/*  A library to output the right key shortcut in any common app. 
Given a global variable babble_mode to show the environment and a 
key that calls the paste macro, do the right type of paste. 
Setting the context is done by another macro, or TBD interaction with the host. 

Huge thanks to https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts
and https://github.com/qmk/qmk_firmware/blob/master/keyboards/planck/keymaps/jeebak/keymap.c
